Abstract: In an automatic guided vehicle system for guiding a driverless vehicle (10) over a predetermined path of travel without any tracks, wires or the like the vehicle is provided with an active optical navigation section (103) for determining vehicle position and bearing by scanning a plurality of beacons (12 to 24) distributed within the zone of travel of the vehicle, a passive ground navigation section (105) including a gyrocompass (58) for measuring changes in bearing of the vehicle and a wheel encoder (62) for measuring distance travelled by the vehicle's steering wheel. Memory onboard the vehicle contains a series of path vectors which define a predetermined path of travel for the vehicle. The ground navigation section updates vehicle position and bearing as determined by the optical navigation section. A programmed onboard computer (100) includes driver software for generating steering data so as to guide the vehicle over a corrective arc path from its position and bearing, as determined by the navigation sections, to the desired position and bearing as indicated by a stored path vector.

Abstract: A combinational weighing system with a plurality of article batch handling units is controlled so that a high-speed dual or multiple packaging unit can be coupled and its capability can be utilized advantageously. For each cycle of the system operation, three or more combinations are selected by combinational computations on the weight values of article batches and they are discharged to the packaging unit through two discharge routes or more but fewer than the number of the selected combinations. This has the effect of discharging through each discharging route more than one per cycle.

Abstract: A temperature-sensitive crystal resonator 1 exhibits two mutually parallel surfaces 2 of approximately the same size which form a predetermined angle of interception with an x-y-z coordinate system of the quartz crystal formed by one electrical, mechanical and optical axis each; the angle  phi  enclosed by one of the two surfaces 2 and the electrical (x) axis is located within a tolerance range of +1 DEG  and -1 DEG whereas the angle  theta  enclosed by one of the two surfaces 2 and the optical (z) axis is either within a range from 3 to 6 DEG  or within a range from 68 to 72 DEG . 
<??>Since the change in temperature coefficient per change in angle  theta is only relatively small due to the maximum or minimum characteristic in the range from  theta   SIMILAR  4 DEG  and  theta   SIMILAR  70 DEG , crystal resonators having a virtually constant temperature coefficient can be produced within a technically easily handled tolerance range in series production.

Abstract: An x-ray lithography system is disclosed in which x-rays (56) are generated by directing a high energy laser beam against a metal target (26) to form an x-ray emitting plasma. The x-rays from the plasma are then directed through a mask towards a resist covered wafer (58) to cause a patterned exposure on the wafer resist coating. The mask, the portion of the target which the laser beam strikes and the portion of the wafer to be exposed are all within an evacuated chamber (22). The laser, prior to entering the chamber,is split into two separate beams (24, 24A), each of which are focused and directed through a window (70, 72) in the side of the chamber towards the same spot on the target. Apparatus, including an air bearing, seal and positioner, is provided to move the target at periodic intervals. Similar apparatus is provided to move the wafer from exposure section to exposure section. The laser beam system includes a face pumped laser beam amplifier (188) and unidirectional beam expanders (232, 280) to allow the maximum energy to be transferred to the laser beam by the amplifier. A series of two or more laser pulses are provided in order to maximize the energy obtained from the laser amplifier.

Abstract: Animal derived cells, especially erythrocytes, have been artificially modified (and referred to as engineered erythrocytes or RBCs) so as to incorporate in their plasma membranes an antigen, CD4 protein derived from lymphocytes, which will cause them to selectively seek out and fuse with other cells that are infected with a virus, especially the AIDS virus. These modified cells can be further altered so as to contain in their cytoplasm a cytotoxic agent which, after the cell has fused with a target cell, will result in the pooling of their respective cytoplasms and the death of both cells, with subsequent removal by the reticuloendothelial system. The invention also includes the production and use of similarly modified liposomes. The present invention can be used as a treatment of Acquired Immune Deficiency Syndrome (AIDS).

Abstract: In a switched mode power supply, an output switch is coupled to the primary winding of a transformer and to an input supply voltage derived from the AC mains voltage. A driver stage is coupled to the output switch and to a switched control voltage for producing on-off switching of the output switch between conduction and cutoff to generate a pulse voltage in a secondary winding of the transformer. A supply circuit including a rectifier is coupled to the pulse voltage for generating an operating voltage. A control circuit, responsive to the feedback of the output voltage, modulates the control voltage in a manner that varies the on-off switching of the output switch to stabilize the operating voltage. A bias voltage, derived from the AC mains voltage, and available during a startup interval of the power supply, is coupled to the driver stage during the startup interval. The bias voltage inhibits conduction of the output switch until sufficient time has elapsed after initiation of startup to enable the control circuit to generate a control voltage that is adequate to safely produce the on-off switching of the output switch.

Abstract: In the trigger arrangement (1), which is particularly suitable for use in oscilloscopes comprising, for example, a cathode-ray tube as display device, a trigger output signal (10) is layed from a trigger input signal (6 ) after the trigger arrangement (1) is released by a release signal (8). Use is made of a series-combination of three bistable elements (2,4,16). The trigger input signal (6) is applied in parallel to the bistable elements (2,4,16) and the trigger output signal (10) is obtained after the output of each bistable element (2,4,16) has successively changed its state, a difference occurring between the switching levels of the successive bistable elements (2,4,16) when the trigger input signal (6) is applied to the bistable elements (2,4,16)  via  differential amplifiers - assumed to be included in the bistable elements (2,4,16). The first two bistable elements (2,4) form an accurately defined release signal (17) for releasing the third bistable element (16). The instant of release of the third bistable element(16) is thereby prevented from coinciding - up to very high frequencies - with the instant at which the trigger input signal (6) can cause the output (23) of the third bistable element (16) to change its state after release of the third bistable element (16). By means of an oscilloscope provided with such a trigger arrangement, "jitter"-free signals can be displayed up to very high frequencies.
